Next GeosolutionsNext Geosolutions, an independent geoscience and engineering service provider, has been awarded two survey contracts for the North Sea Link interconnector (NSL) project, the first electricity link between UK and Norway.

The first contract, due to commence in April 2017, will see Next Geosolutions provide cable protection survey work for Statnett, the Norwegian transmission system operator.

The two week workscope will involve cable inspections for the Skagerrak electricity transmission system and NorNed power cable interconnectors. The interconnectors will link the electricity transmission systems of different countries, with subsea cables utilised for the NSL, passing through Norwegian and British waters.

The second contract is due to commence in May 2017 for a period of three months. It will involve Next Geosolutions carrying out offshore cable route survey, unexploded ordnance (UXO) survey and route preparation techniques.

Each survey will be performed with the same mobilisation and demobilisation delivered by Next Geosolutions’ new dynamic positioning (DP) Class 2 multi-purpose supply (MPSV) vessel - the Ievoli Cobalt. The vessel is currently fitted with a Schilling-Ultra Heavy Duty (UHD) Work-Class Remotely Operated Vehicle (ROV) and McArtney Focus 3 Remotely Operated Towed Vehicle (ROTV).

The Focus 3 ROTV will deliver high-resolution datasets for route design and engineering, as well as subsea asset inspections utilising its simultaneous sensor package.

Carlo Pinto, Next Geosolutions’ sales and marketing director said: “We’re extremely proud to have the opportunity to contribute to the NSL electricity link which, once completed, will be the longest subsea interconnector in the world.
“This project is an important part of Europe’s future electricity system. The interconnectors allow countries to trade power, helping to ensure safe, secure and affordable energy supplies, so it is crucial these are surveyed to a high standard.”

With a planned capacity of 1,400 MW, the interconnector will be able to transport enough electricity to power nearly 750,000 homes helping both countries to meet their domestic energy demand.

National Grid North Sea Link Ltd, a National Grid subsidiary, and Statnett are working together to construct the subsea interconnector, when constructed this will consist of approximately 720km High Voltage Direct Current (HVDC) cable. The developers plan for the link to be operational in 2021 connecting Kvilldal in Norway and Blyth in the UK.

WSP | Parsons Brinckerhoff recently announced its appointment by National Grid to provide cable manufacturing quality and inspection services on the €2bn project.
